f My invention pertains to a machine for makving ne shavingsof ice to obtain a snow-likeap.-

pearance ofthe ice, the machine being'f'rprinci-v pally adapted'for serving shaved icefor'cooling An object and feature of my invention-is the construction of a .machine "which isv compact and may lbe used on a soda water fountain counter or the like, and which lends itselfl to rapid shaving of the ice, the power being derived from an electric motor. Also, another object-'I have had inmind is to construct a machine which will be silent in operation, whichr is easy. tocontrol'and manipulate to obtain ice shaved inthe manner desired, and to shavethe ice so rapidly that it cannotbecome soggy'with water, Vwhichis the case `with `certain ice shaving` machines'linwhich the ice shavings become saturated with water from the melted ice.

VIn a machine ofthe above type, certainobjects and featuresfof my invention fromv a mechanical standpoint is the construction 'ofy an ice shaving machine in whicha vertical cylindrical ice shaver is used, this having blades.` Thev shaver 'is'hollow so that Ythe shavings are forced from the outside of the cylindrical shaver to the center v`and then drop in Va glass or other 'receiv-v ingvessel. f 1'- f lAnother objectand feature-of my invention in regard to the shaver is the uselof. a press or pressure device which may press -tlleicevagainst the shaving cylinder at any desired pressurefin order to force the shaved ice through rapidly or more slowly. f i

In connection with the use ofthe ice press, a further object and feature ofmy invention is having thisfrotatable` so that 'the pressingsurface may bev removedfrom the shaving cylinder to allow deposit of ice, this ice dropping-into the below the foraminated plate tocatch water vdip-L y pings, andv afdraink .pipe `l5 is connected 'to the l bottom ofthe sink. A substantial intermediate space between the pressure face andthe cylinder from anice chamber or biv shaving cylinder. Y 1 y Another object and feature in regard to the' ice" chamber and the'ice! press is the provision of a slopingY surface or slide to allow the ice to slide downwardlyand drop into -ar space opened by the movement of the ice pressvwhen retracted, such `ice/press being retracted'-underneath-said ice slide. The general construction of the Vice chamber, slide, and the'location vof the. shaving cylinder is, preferably7 to use a-vcylindrical container structure with a rotatable hollow cylinder in the center. This hollow cylinder a't'the bottom carries 'the ice press which Amay be housed underneath the slide which is formed in the' mann located aboveV the ner of ahelix to allow vdropping of the ice to lill the.v space between the. end of the` slide and thev shavingv cylinder. which is located at one side oi the machine. A .Another feature of my. invention relates to the controlof the ice press in the manually operated machine, this preferably being done. by movingV a rod or lever `which projects. from.,r preferably, the iront of the machine, and this causes the ice press .to rotate vonk its axis to `bring the lumps ofi ice into Acontact with the cutting blades, on the periphery of the shaving l cylinder.

Another detailed feature of my vinvention relates toi theuse or" a cleaning blade iittediinterf nally of `rthe shaving cylinder to scrape. ,the ice shavings, from the interior wall of such cylinder` ving drawings, inwhich:l l

Fig.'6 is a horizontal det-ail section on'thefline 6-61 offFig; '2 in the' direction of the. arrows, through theshaving cylinder. Q

, f .In constructing'rny invention' I-utilize-a pcd-- estal 11 which `may rest'iion the counter of a soda water fountainL installati-en This hasjfa baseplat'e 12, one section-fof whichf-is cut out and has a Aforam'inate'd plater 13. A sink '14 is ing' an cuter wall 21 and an inner wall 22 "spaced apart, havingspa'cing' rings 23 at the bottom and 24 `atthe top.' Thespacing ring at thetop is part of aspide'r 25,'thi's spider vhaving arrns26. A detachable cover 2%? forms' a 'cover for the container and allows inserting of the ice press designated by the assembly 55.

Inside of the container, forming a xed structure, there is an ice chute or slide 28. This has an upper edge 29 and a lower edge 30. It will be seen on reference to Fig. 4 that these edges are slightly over 120 degrees part. They can have a small angle, if desired, but the slide 28 which forms a helix should be greater than a half circle and as large as possible. Extending downwardly from the edge 29 there is, preferably, a radial and vertical surface 31. At the lower part of this surface there is an extending lip 32 to divert the ice, as hereinunder detailed. The support for the ice chute or slide is illustrated as having a solid body structure 33 with a curved segmental wall 34. This wall at the bottom rests on the floor plate 35 which is part of a casting forming the base 19. The chute or slide at its outer periphery 36 is preferably welded to the inner wall 22 of the container. The metal of this slide must be suiciently stiff and rigid so that it will form a strong structure to support ice packed above this slide, the stack of ice being indicated in Fig.

1, the ice being inserted through the lid and bel tween the arms or ribs of the spider 25.

A rotatable cylinder 37 is illustrated as having a sheetmetal cylindrical wall 38 and upper and lower ends 39, these having stub shafts 40 and 41. These stub shafts. are journaled in a hub 42 at the top forming part of the spider. 25 and a hub 43 at the bottom forming part of the bottom plate 85. Bushings 44 are usedv in the journals. The stub shaft 41 at the bottom has a gear arm 45connected thereto with a segmental gear 46. Meshing with this gear is a rack 47 which is supported and guided byV a straight guide 48 securedto the under side of the base plate 35. A bell crank 49 pivoted at.50 yon the under side of the plate 35vhas Aone arm connected to the rack 47 and another to a link 51, which link is connected to a slide rod 52 operating through a guide 53 in the frontv of the base 19. This rod has a hand grip end 54. Such latter construction is for the purpose of rotating a cylinder.

This cylinder 37 forms the mounting for the This ice press. has an inner wall 56 secured to the cylinder wallv 88 by rivets or the like, an outer wall 57 which is contiguous to the inner wall 22 of the container, and an upper flat connecting surface 58. 'The upper surface has ar clearance underneath .the lower edge, 80 of the ice chute or. slide 28. 'This also, preferably, has an enclosed end 59 at the back and a curved closed end 60 at its front or exposed end. VThe curvature:l at thefront wall is part of a circle to conform to the cylindrical ice shaver described hereinunder. :By this construction the ice press, by operating the handle 54, may be moved completely underneath the ice chute or slide 28 and when so moved it leaves a large open space from the line `29 of the chute to the line 30 and from the top of the container to the base plate 35 in .which ice may be stacked as well as the ice being stacked on top of the slopingA surface of thechute.

,The ice shaverf designated by the assembly numerall has a cylindrical construction 62 next to its side walls. .Thishas a closed top 63 with a stub shaft 64 extending upwardly (note. Fig. 2), which stub shaft is mounted in anti-friction bearings 65 in a socket orrecess 66 in the metal bodyA 33 of the ice chute orV slide. This cylinder extends through'an opening 67 in the plate 35 of the base. It is illustrated as having a reduced section 68 at the bottom'iwhich is journaled in a bottom bearing 69, which bearing is bolted to a lower plate 70 forming part of the casting of the base 19.` A pulley wheel 71 is keyed onrthe section 68 of the cylinder and there' are thrust bearings 72 between this pulley and the plate '70. This supports the weight of the cylindrical ice shaver. The bottom of the cylinder has an out` standing bead 73. On the upper edge of the hub of the pulley 71 there is a water deliecting wing 74. Y

The ice shaving cylinder is providedl with a series of slots 75. These are illustrated as being narrow at the outer part 76 and wide at the inner part 77, thus giving an enlarged clearance. At the outside of the cylinder there are recesses 78 with shaving blades 79 attached by screws` or the like. These blades direct the shavings through the slots 75. In the construction illustrated, there are two diametrically opposite shaving blades at the bottom of the cylinder, two at the top in alignment therewith, and an intermediate pair at right angles to the irst twov The cylindrical ice shaver is rotated by means of a belt 84 which is driven by a driving pulley 85 attached to the shaft 86 of the electric motor 87. This motor is illustrated as being bolted to the front wall 18 of the stand 16, the shaft 86 extending upwardly through an opening 88 in the bottom plate 70. A receptacle illustrated as a glass 89 may rest on the foraminatedplate 13 directly below the ice shaving cylinder to receive the shaved ice.

An annular trough 90 is secured underneath the plate 35 to receivethe drip from the ring 74 and from this trough there is a waste pipe 91 which may `lead in any convenient directionrto discharge the sink 14. This carries any water from the ice which trickles down on the outside of the cylindrical ice shaver.

In construction and operation of my invention, when the ice container is rst lilled, by removing the cover 27, with broken ice, the ice press 55fis moved by operating the handle 54, the bell crank 49, the rack 47, and the segmental gear 46, and by turning the cylinder 37 so that theY ice press is housed as completely as possible underneath the ice chute or slide 28. As above mentioned, this allows the ice container to be lled between the cylindrical ice shaver and the front wall 6l) The shavings cut by theA blades 79 pass inwardly through the slots 76, and should these tend to cling to the inside surface of the cylindrical cutter, they are removed by the scraping blade 81 and dropped through the lower open end of the cylinder and through the spout 80 into the recepi-r tacle 89. The electric motormay be ystarted and stopped by any suitable control switch; When the front face of the ice press approaches thecylinf dricalice shaver, the motion may-be reversed andthe ice press again' housed, allowing' the Yi'cefabove the pressl to fall downwardly into the 'space between'the press andthe shaving cylinder. A cer` tain amount oi this ice'will slide Von the ice'chute`28 so that the ice may allbe used up, the amount rst shaved being" thatbetween the shaver and the ice press, and subsequently the ice resting on top of thechute. Itis obvious that by varying thepressu're of theicepress on'the broken ice v that this may be' forced through the cylindrical shaverv at'varying speeds and thus shave the ice to a coarse or a fine degree;v and as soon as the f pressure is released the machine will cease shaving the ice. Y y

' From the above descripticn,'-together with the drawings, it nwill be seen that inv my invention, therevare certain important features such as the cylindricalice shaving cylinder which `has slots therethrough being made hollow and cutting blades operating on the periphery, This, in rotating on its vertical axis, and having an opening at the bottom, permits a direct downward discharge ofthe ice which has beencut into shavings.

Another characteristic feature is the employlment of the ice press, this being designed to vrotate in an annular space, such space being between the rotatable cylinder and the inner wall of the container. This cylinder is, in effect, a vertical shaft, and the `rotaticnof such shaft forces the ice back between the ice press and the shaving device into contact with such latter device.

Another important characteristic of my invention is a cover structure over part ofthe lannular chamber between the cylinder 37V and the container wall. This allows partly housing of theice press for packing of the ice betweenr the press and the shaver, 'and also when the initial quantity of ice has been shaved the ice onthe top of this cover, which is formed in the manner of an ice chute, may drop` into the lower space and then be forced against theshaving cylinder.

Various changes may be made in the details of construction without departing from the scope of the invention as defined by the appended claims.
